Benzylamine → 5-Amino-1-(4-fluorophenyl)-N-(3,3,3-trifluoro-2-hydroxy-2-{[(phenylmethyl)amino]methyl}propyl)-1H-pyrazole-4-carboxamide

Participants

Reaction Steps

To 5-amino-1-(4-fluorophenyl)-N-{[2-(trifluoromethyl)-2-oxiranyl]methyl}-1H-pyrazole-4-carboxamide (15.3 g) in dioxane (250 ml) was added benzylamine (5.76 ml). The mixture was stirred at room temperature for 16 hours and then for a further 4 hours to ensure the reaction was complete. The orange solution was concentrated in vacuo to give an orange oil (which still contained some solvent). The oil was dried on the vacuum line to give the title compound (20.50 g) as an orange solid.
